Vintage voltage reference

Hi everybody

I've just got a vintage voltage reference from ebay.
I'm looking for specifications.
How can I test the sucker without releasing the magic smoke?

It appears Dynage is still in business. Maybe an email to them might be your best bet?

I've sent a email to Philip Dooley most likely the last mohican there, as Dynage was dissolved in 2010!

In 2010, Oakleaf, Inc. was dissolved following the death of its founder and CEO, Sidney Oakleaf. Support  and repair for Dynage's existing product line and new product design is being handled by Philip Dooley on a contract basis.  Philip Dooley was chief engineer for Dynage for over 30 years.

Meanwhile I found a interesting article from the famous Jim Williams lab notes, where a Dynage module is used in the ultra stable voltage source of a high performance differential voltmeter.
